The Plank Position is no doubt one of the best Ab Exercises. Not only does it strengthen the abdominal muscles, but also works all the core muscles – the back, hips, etc.
Here’s your challenge
1st — Get into plank position and hold form for as long as you can. Place a clock so you can easily see it, as you’ll need to keep track of your time. Repeat this task 3 times and take note of your longest time.
2nd — every other day for four weeks repeat this exercise. Your goal is to stay in position longer and longer with each effort. By the end of the four weeks you should have tripled your longest time.
Plank Pose Basics — Start by lying face down on the ground or use an exercise mat. Place your hands or your elbows/forearms underneath your chest. Hands/elbows should be directly under your shoulders. Prop yourself up to form a bridge using your toes. Maintain a flat back and do not allow your hips to sag towards the ground. Hold this position focusing on tightening your abs by drawing your belly button to your spine. Hold until you can no longer maintain a flat bridge.
Beware of Cheating — Remember to not let your hips and back sag. This exercise will only be effective if you work to maintain a flat line from your shoulders to your feet. You might want to start in front of a mirror to learn the technique.
If you have any questions please ask. I look forward to hearing how you do.
